Hey, I have a b16 in a crx, and had been driving the current setup for about a year, with no problems. The issue I have now started suddenly, and I'm not sure what the deal is. My car drives fine when it's cold, but after 10 minutes of driving, the car will try to stall under acceleration between RPMs of 1 - 2.5k (by stall, I mean it feels like repeatedly hitting a brick wall). To keep it from stalling, I have to keep the clutch 1/2 engaged until I'm over 2.5k.

It also develops a semi-erratic idle. After driving for about an hour, I thought it was going to stall when I was at a stoplight, and I had to gas it, even with the clutch punched in.

I'm fairly clueless. It doesn't lag under WOT (at higher RPMs), and the dizzy / spark plugs are new. I DID have a problem with an alternator that was putting out extremely high voltage, I don't know if some sensors could have been fried.

Any suggestions on what to check, or process of elimination ideas would be fantastic.

Thanks,
Matt

 

Is your ECU chipped?

 

Yes, it's a Phearable chip. Think I should swap out the ecu and see how it runs?

 

try that first, i had a problem just like with on of their ecu's. I sent it back and they fixed it for free.
